Cinnarizine Impurity 7 CAS CATO-C4X-13987 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Cinnarizine Impurity 7.

Cinnarizine Impurity 7 (CAS CATO-C4X-13987) is a certified pharmaceutical impurity reference standard with the molecular formula C18H18O and a molecular weight of 250.33 g/mol.

The molecular framework of Cinnarizine Impurity 7 (C18H18O) is characterized by a steroid core, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.

CATO manufactures Cinnarizine Impurity 7 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
